Mutations in the tricarboxylic acid (TCA) cycle enzyme fumarate hydratase (FH) are associated with a highly malignant form of renal cancer. We combined analytical chemistry and metabolic computational modelling to investigate the metabolic implications of FH loss in immortalized and primary mouse kidney cells. Here, we show that the accumulation of fumarate caused by the inactivation of FH lead...
The integral membrane protein fumarate reductase catalyzes the final step of anaerobic respiration when fumarate is the terminal electron acceptor. The homologous enzyme succinate dehydrogenase also plays a prominent role in cellular energetics as a member of the Krebs cycle and as complex II of the aerobic respiratory chain. Fumarate reductase consists of four subunits that contain a covalentl...
The chiral bicyclic lactam (2) derived from levulinic acid and (S)-valinol is sequentially alkylated and then cleaved to 2,2-dialkyl levulinaldehyde (5) which is cyclized to the title products (2) in > 99% ee.
BACKGROUND Tenofovir alafenamide, a tenofovir prodrug, results in 90% lower tenofovir plasma concentrations than does tenofovir disproxil fumarate, thereby minimising bone and renal risks. We investigated the efficacy, safety, and tolerability of switching to a single-tablet regimen containing rilpivirine, emtricitabine, and tenofovir alafenamide compared with remaining on rilpivirine, emtricit...
OBJECTIVE Iron therapy may reinforce intestinal inflammation by catalysing production of reactive oxygen species. The effects of oral ferrous fumarate and intravenous iron sucrose on clinical disease activity and plasma redox status were investigated in patients with inflammatory bowel disease (IBD). MATERIAL AND METHODS Nineteen patients with iron deficiency anaemia and Crohn's disease (11) ...
Human mitochondrial NAD(P)+-dependent malic enzyme (m-NAD(P)-ME) is allosterically activated by the four-carbon trans dicarboxylic acid, fumarate. Previous studies have suggested that the dicarboxylic acid in a trans conformation around the carbon-carbon double bond is required for the allosteric activation of the enzyme. In this paper, the allosteric effects of fumarate analogs on m-NAD(P)-ME ...
The blood flow changes in the optic nerve head in adult albino rabbits following intravenous administration of brovincamine fumarate, an improver of cerebral circulation and metabolism, were investigated employing the hydrogen clearance method. In the brovincamine fumarate (0.1 mg/kg)-administered group, the blood flow in the optic nerve head increased soon after injection and reached the maxim...
